Most Helpful Girl

Why on earth would you do that? Just let her move on with someone else and you move on too - you have made yourself look to her (and probably her new bf) like a jealous, obsessed ex that can't let go ... it really doesn't paint you in a good picture. You don't owe this new guy anything, just move on, forget about her and don't contact her, her boyfriend or anyone they hang around with and hopefully the whole situation will die down and she won't take it any further. You will find someone better suited to you, get yourself out and have fun.

Possibly, I'm based in UK so couldn't say but it was a pretty stupid thing to do as you have put yourself in a compromising position ... you can't say you didn't mean anything bad as NOBODY would believe that, it's downright spiteful. If I was you I would avoid all conversation of being sued, give it a few days and contact her and her new boyfriend and apologize and try to diffuse the situation
